some actual width data for Clement XPlor tires on my rims
MSO 40mm on open pro rims 14.5mm inner width @ 30psi
37.5 at bumps
35.4 at sidewall
On Kinlin 279 rims (17mm inner)
USH 35mm On open pro
on Kinlin 279 rims at 50psi
Tires are fairly new, under 200 miles.
So yes, wider rims makes your tires a little wider.
Thanks for sharing...looks like I could put the MSO 40's on my bike without any tire clearance issues. Out of curiousity, have you run the MSO 40s much on your 14.5mm rims? I'd be interested to know if you encountered any stability issues...according to all of the charts, that tire is too big for that rim (but I'm considering doing something similar in the near future).
Darn good question. Usually you would want at least a 17mm rim for a 40mm tire.

I did ride them a little on the open pro rims, probably less than 50 miles. The tires stayed on the rims just fine, I was running low pressure, probably 25-30, and riding mostly offroad
oh, I see, you mounted them just out of curiosity and to measure the inflated dimensions... and now you're riding them on the wider rims.

Have bike, will travel
I'm getting a width of 39.3mm at the sidewall and 39.7mm at the knobs with the 120 tpi MSO mounted on Velocity Dyad rims. These tires have only been inflated for 48 hours, and I expect them to grow a few a small amount over the next few weeks. The Dyad is 24mm wide, Velocity does not publish the inside width on its website.
